Passion flower (Passiflora incarnata) is a flower that has been traditionally used to treat insomnia. It does not result in feeling hungover or spaced. Passion flower is believed to be effective in treating insomnia caused by stress, nervousness and overwork.

Steps:
Prepare a tea of passion flower one hour before bedtime.
Brew the tea as follows:

Add one teaspoon of dried passion flower herb to one mug of boiling water.
Leave to infuse for 15 minutes.
Drink in a relaxed environment a half hour before you go to bed. Avoid using any stimuli such as TV, computers, or anything else that keeps your mind too active. A book, soft music, and dim lighting are a good accompaniment.
If you have a fluid extract or tincture, use 10 - 30 drops three times a day for the fluid extract, 10 - 60 drops three times a day for the tincture, or as recommended on the tincture label. It can also be taken in the form of a gel capsule; follow the instructions on the label.
